SMOKING rrrn.

Application filed. April 1, .1925. Serial No. 19,809.

To all whom it may concern: 7

Be it known that I, 'HERMAN W. K lo PP- MAN, a citizen of the United States, res ding at Chicago, Cook County, Illinois, have invantages of a substantially long stem, for instances, the advantage of a relatively cool draught atthe mouthpiece and the deposit of a materially large portion of the tarry and other products of combustion on internal walls of the pipe structure whereby the smoke entering the mouth is singularly clean and free of objectionable matter. It is an object to provide a pipe having such advantages and. according to which the various internal pipe surfaces may be easily cleaned and maintained sanitary and in condition to, provide what the smoker'in well-known figurative language would term a. 7 sweet smoke. It is an object also to provide a pipe according to which various parts may be readily assembled and dissociated from each other from time to time in an easy and simple way. .An important object is to provide a pipe having advantages as mentioned and in a form notably easy of manufacture.

In the drawings, Figure 1 shows my improved pipe in a highly advantageous form in top view; Fig. 2 is a medial vertical section on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary top view with the bowl and bottom closure removed; Fig. 4 is a vertical sectional View through the walls of the easing as indicated bythe line 4-4 of Fig. 3, the section being on a circular, line midway between the outer and inner surfaces of the casing wall and the section .beinglaid out flat, showing clearly the sinuous and con- .tinuous character of the relatively long channel for smoke within the casing walls;

and Fig. 5 is a fragmentary side view similar to the sectional view of Fig. 2 but showing the removabletop and bottom members inverted with respect to their relative positions in Fig. 2.

In smoking pipes the head or body as a whole containing the termed the bowl. According to such nomenclature the bowl in the present instance comp swas 19. the ar P and th fire pot is usually bottom closure 12. The mouthpiece 13lis shownv as extending frictionally into an opening in a stem-like projection 14 integral with the bowl. The shank or stem 14 is bored at 15 to provide a hollow interior or smoke channel, and the mouthpiece 13 has the usual channelv 16. In the accompanying claims the stem therein designated may be considered the shank part 14 or the shank and mouthpiece combined, or, in instances where the mouthpiece maybe inserted 'directly into thebowl, the mouthpiece alone would constitute the stem.

The casing 10, together with the integral shank part 14, may be of any suitable wood, composition, or other material, andmay be formed according to we ll-known manufacturinginethods and means. In the drawings the casing is shown as a cylindrical body having a cylindrical hollow interior 17 open at both ends. The accompanying drawings are scaled from one of my pipes and therefore show suitable proportions, although the present invention may be embodied in pipes of various shapes and proportions of parts.

It will be noted that within the walls of I the casing 10, and between the inner wall 10 and the outer wall 1O. thereof, I provide a considerable number. of longitudinal channels 18 side by side, in parallel arrangement with each other, andcoming one after the other from one end of the casing to the other. 7 I

' From the dotted lines in Fig. 3 and from the full lines in Fig. 4 it will be noted that an elongated opening 20 is made in the cas' ing wall leading from the hollow interior 17 to'that one of the channels marked 18 which is immediately adjacent to a channel in line with the stem and on the line 4 of Fig. 3. From Figs. 3 and 4 it will also be noted that between the adjacent channels 18 and 18", and at the top as shown in these figures, a recess21 is formed placing the channels 18 and 18 in communication with each other. From Fig. 4 it will be seen that between the channel 18 and the channel 18, 7

and at the bottom as shown in that figure,

there is provided a recess 22 placing the channels 18 and 18 in communication with I each other. Also that between the channels 18 and 18 and at the top as shown in Fig. 4, there is a recess 21? placing these channels in communication with each other. In the'same manner the c ne s .18 adjacent greatly reduced. conducted principally to the flange 27 and to each other are placed in communication with each other at one end or the other of the casing whereby these channels are in series and provide, when the top and bot tom closures are applied, a sinuous and con tinuous channel for smoke leading from the hollow interior 1'? up and down and advancing until the exit opening- 25 is reached leading into the hollow interior of the stem.

Tracing the smoke channel at its latter end it will be noted from Fig. 4 that between the channels l8 and 18 there is a recess 2%, and that between the channel 18 and 18 there is a top recess 21", and

that the discharge opening 25 is in the reoess 18 7 The firepot 11 is shown as having an annular flange-like extension 27 overlying the normally upper end of the casing walls 10,]the flange being recessed to accommodate a gasket 28, which may be of. fibre or ofany other suitable material. The fire pot and flange 27 are preferably made integral with each other, and may be of wood or any-other suitable material. Several openings 29 place the interior ofthe fire pot in communication with the hollow interior 17;

The bottom closure 12 is provided with an upstanding central projection 30 having its vfree end inscrew-threaded engagement with the fire pot 11. It has also an annular part 31 overlying the bottom walls of the casing, and a gasket 32 therein cooperates in maintaining a tight fit at this joint. The annular trough 33 collects tarry deposits and condensedwater vapor arising from combustion'inthe fire pot and cooperates to prevent oozing at the gasket 32 shouldthe joint not be maintained tight by theuser.

The fire pot is spaced from the inner surface of the casing walls to a materially large extent, the outer walls of the fire pot preferably tapering to provide clearance except at the top where the fit is sufficiently closeto center the fire pot with the casing. This clearance or spacing provides a heat insulating medium between the fire pot and the casing and the transmission of heat to the casing by conduction is therefore Heat'from the fire potis to the projection30, and such conducted heat is dissipated to a large extent into the open: air.

The .smoke first passes into the hollow in terior 17 where a preliminary cooling and the deposit of carbon, tars and water vapor' takes place. It then passes into the long winding channel described, and thence to.

the mouthpiece. The winding channel illustrated is about thirty five inches long and its cubic capacity'is such that a single 1 draught at the mouthpiece does not nearly exhaust its air-'and-smoke contents at a r or fifth draught thereafter.

the sinuous channel is therefore quiescent given time. Ordinarily some smoke present in, the bowl at a given time does not reach the mouthpiece until the third, fourth The smoke in times )refer the underslun arrangement The user may at as shown in Fig. 2 and at other times the one shown in Fig. 5. The entrance'opening 20 (Fig. l) beingelongated, a substantially large opening is providedvfrom the chamber 17 in'either position ofythe'fire pot.

It is apparent that unusual conditions exist for cleaning all of the'inner surfaces of the bowl. With the top and bottom closures removed the ordinary long, slender andfuzzy pipe-stem cleaner may be passed through the channel 18.

I, contemplate. as being'fincluded in the present invention. such changes, modifications and departures from what is herein specifically illustrated and described-as fall within the scope of the appended claims.
